An image sensor may comprise one or more light emitters and/or one or more light receivers.

In an exemplary operation, the monoscopic video camera array 110 may be operable to concurrently or simultaneously capture a plurality of 2D monoscopic images and corresponding depth information. For example, the monoscopic video camera array 110 may capture a 2D monoscopic image/video via the image sensors 118.

The image mapping function may be determined by matching or fitting the captured 2D monoscopic images/video and the captured corresponding depth information to view angles and associated lighting conditions of the monoscopic video cameras 110 ₁-110 _(N), In this regard, different view angles and associated lighting conditions may be converted or correspond to different sets of 2D images/video data and corresponding depth information. In other words, the video processor 120 may interpret the captured 2D monoscopic images/video in different image planes depending on view angles and associated lighting conditions. An image plane may be assumed to be coincident with the XY-plane of a XYZ coordinate system, and is parallel to the XY-plane at distance d, where d>0. The video processor 120 may be operable to compose or generate 2D and/or 3D images/videos from the captured 2D monoscopic images/video depending on view angles and associated lighting conditions. For example, for a given view angle, the video processor 120 may utilize the determined image mapping function to map or convert the captured 2D monoscopic images/video and the captured corresponding depth information to a specific set of 2D image data and corresponding depth information for the given view angle. The video processor 120 may generate or compose a 2D and/or 3D image/video for the given angle utilizing the resulting view-angle dependent 2D image data and corresponding view-angle dependent depth information. The generated 2D and/or 3D image/video for the given view angle may be presented or displayed to the user via the display 132 and/or the 3D video rendering device 136.

A point Q(x,y) in the XY-plane 201 may represent or correspond to an image pixel in one of a plurality of 2D images captured by the monoscopic video camera array 110. The image engine 122 may be operable to map the point Q(x,y) in the XY-plane 201 into different image planes depending on view angles. For example, for given view angles ⊖₁ and ⊖₂, and associated lighting conditions ξ₁ and ξ₂, the image engine 122 may output or provide different depth values z₁(⊖₁, ξ₁) and z₂(⊖₂, ξ₂) for the point Q(x,y) in the XY-plane 201. In this regard, the point Q(x,y) in the XY-plane 201may be mapped or projected to the point P₁(x,y, z_(i)(⊖₁, ξ₁)) in the image plane 202 and to the point P₂(x,y, z₂(Γ₂, ξ₂)) in the image plane 202, respectively, for video rendering and/or playback.

The parameters ⊖₁ . . . ⊖_(N) are corresponding view angles of the monoscopic video cameras 110 ₁-110 _(N) for the scene in front of the monoscopic video camera array 110.

The image engine 122 may model the captured 2D monoscopic images 310 ₁-310 _(N) and the captured corresponding depth images 320 ₁-320 _(N) to fit or match the known view angles ⊖₁ . . . ⊖_(N), respectively. For example, the image engine 122 may perform regression analysis on the captured 2D monoscopic images 310 ₁-310 _(N), the captured corresponding depth images 320 ₁-320 _(N) to fit or match the known view angles ⊖₁ . . . ⊖_(N) so as to determine or establish a relation among intensity and/or color information, depth information and view angles for the scene in front of the monoscopic video camera array 110. In this regard, the image engine 122 may convert or map the captured 2D monoscopic images 310 ₁-310 _(N) and the captured corresponding depth images 320 ₁-320 _(N) to the view angles ⊖₁ . . . ⊖_(N). The image engine 122 may provide or output different 2D monoscopic images and corresponding depth images depending on different view angles. For a given view angle, β, the depth image 322 and the 2D monoscopic image 324 may be provided by the image engine 122, respectively.

In this regard, the image engine 122 may perform regression analysis on the captured 2D monoscopic images and the captured corresponding depth information for the modeling. For example, the image engine 122 may match or fit the captured 2D monoscopic images and the corresponding depth images to view angles of the monoscopic video cameras 110 ₁-110 _(N) to determine the image mapping function. In step 408, it may be determined whether image/video rendering for a given view angle is needed for the captured 2D monoscopic images. In instances where image/video rendering for the given view angle is needed for the captured 2D monoscopic images, then in step 410, the image engine 122 may determine or calculate 2D image monoscopic image/video data and corresponding depth information for the given view angle utilizing the determined image mapping function. In step 412, it may be determined whether 3D image/video rendering for the given view angle is needed.
